Description
A kind of method for surface reinforced treatment of metal part, present method relate to adopt the thermospray means at metal part surface coated strengthening layer improving metal parts working life at high temperature, or the hot operation metal part surface that has worn and torn is carried out repair process.
As everyone knows, the high temperature down metal parts of work use expensive heat-stable material mostly, and for example high temperature steel such as Ni-Cr is made, and the hot operation life-span of improving these parts, very big meaning saved material to reduction factory products cost.The continuous furnace furnace roller used of steel mill particularly and since working conditions abominable damage particularly serious.
Also have before the present invention at metal part surface spraying high-melting-point, the method for surface hardening of high hot strength alloy layer, for example at heating furnace roller surface spraying Ni-Al alloy layer, but because surface strengthen layer and body material bonding properties are poor, strengthening layer is easy to peel off during use, the spy opens clear 49-22343 and has disclosed a kind of elder generation and combine good Ni-Mo prime coat with body material at roll surface matrix spraying one deck, and then spraying Ni-Al alloy layer, the method of the pure Al strengthening layer of final spraying, problem is peeled off in solution, but this art breading complexity, behind the spraying prime coat, to carry out 50 hours thermal treatment of 1000 ℃ of insulations, carry out the secular diffusion annealing of high temperature behind the spray intensified layer again and handle, so technology can not breathe out by a gas, and the cost height, energy consumption is big.
The object of the invention will provide a kind of technology easy exactly, method for surface reinforced treatment of metal part with low cost, also promptly by selecting suitable strengthening layer material and coated order, as long as adopt simple thermospray means, just can be good at metal part surface coated and body material bonding properties, have the strengthening layer of high-temperature working performance again.
Why the metal surface enhanced layer of institute's coated is easy to peel off under hot operation, and its major cause is that two kinds of material coefficient of thermal expansion coefficient differences cause.The present invention is except having the prime coat of well attached performance at substrate material surface coated one deck and body material for this reason, also according to the thermal expansion coefficient difference size between body material and the selected strengthening layer, at the transition layer that sprays on the prime coat more than one deck.It is big more that the coefficient of expansion between body material and the strengthening layer differs, then the number of plies of transition layer is many more, the thermal expansivity of selected buffer layer material will be between body material and strengthening layer, and the thermal expansivity between each buffer layer material also is an increasing or decreasing, in thermal spray process, also can produce diffusion and osmosis between each layer, therefore, after taking this measure, it is poor just to solve between body material and strengthening layer bonding properties, is easy to the problem of peeling off under the hot operation.
Characteristics of the present invention are to combine good metal, alloy or composition metal prime coat with body material at metal part surface spraying one deck, spray the above sintering metal transition layer of one deck at least then, the spray coating metal ceramic strengthening layer is brushed hole sealing agent at last and is carried out the sealing of hole processing again.Technology one gas is breathed out, and the centre need not to carry out any processing.
For body material is the Ni-Cr series heat-resistant steel, prime coat can adopt Ni, Cr, Ni-Cr, Ni-Cr-Al, Ni-Al, metals such as Ni-Mo, alloy, the spraying wire rod or the dusty spray of composition metal, the thickness of prime coat generally is controlled between 0.05～0.15 millimeter, the blocked up bonding strength that can reduce coating self, cross the thin effect that does not have prime coat, transition layer can adopt Ni, Mo, metal-powder and Al such as Al, Si, Ti, Zr, the composite metal ceramic end spraying that oxide ceramics such as Mg are formed, the spraying transition layer is intended to reduce the thermal expansivity of great disparity between body material and the sintering metal working lining, to spray the above transition layer of one deck for this reason, thermal expansivity between each selected transition layer will successively decrease successively, also be that its coefficient of expansion of the first layer transition layer will be near prime coat, and the coefficient of expansion of last one deck transition layer will be near the sintering metal working lining, the number of plies of transition layer is mainly looked the thermal expansivity great disparity degree between body material and the selected sintering metal working lining, differing greatly, then the number of plies is some more, the thickness of each transition layer spraying generally is controlled between 0.05～0.10 millimeter, and is thin excessively, blocked up all undesirable.
It is heat-resistant stability and the good cermet material of high temperature abrasion resistance that the working strengthening layer can adopt metal-powder such as Ni, Mo, Al and Si, Ci, the oxide compound of Ti or the composite cermet selection principle that the carbide ceramic powder is formed, the coated gauge control is 0.07～0.20 millimeter scope, it is poor to cross thin result of use, and blocked up then coating self bonding properties descends.
Owing to there is hole to exist in the sintering metal working lining, therefore also need carry out sealing of hole and handle, sealing material is selected all kinds of resistant to elevated temperatures inorganic sealing hole materials for use.
Each coating can adopt various spraying methods such as plasma or flame plating once to spray successively at substrate material surface and form, and carries out sealing of hole after the cooling again and handles.
It is parts such as straight carbon steel, stainless steel that the present invention also can be applicable to matrix.
Be embodiments of the invention below.
The surface strengthening spray treatment is carried out on surface at 230 millimeters old furnace rollers of process furnace of φ, and furnace roller material is Ni

To be installed in furnace temperature through the new furnace roller of the no strengthening layers in the old furnace roller after the above-mentioned spraying reparation and 21 surface simultaneously and be in 1100～1200 ℃ the stainless-steel pipe solution treatment continuous furnace and use; on probation through contrast in a year; new furnace roller successively has 5 explosions; change midway; condemnation factor is 23.81%; off-test; there are 11 to need to change maintenance on inspection again; scrap with repair rate up to 76%; and three after its surface cermet coatings of old roller of surperficial coated strengthening layer used in 1 year, and the surface has formed one deck in conjunction with the fine and close protective layer of very firm glaze black.After testing, original coat-thickness is about 0.5 millimeter (coated total thickness), and using the back coat-thickness is 0.40～0.45 millimeter, about 0.6 millimeter to the sill diffusion depth of coating metal, use the back coating loss less than 0.1 millimeter in 1 year, improved the hot operation life-span of furnace roller greatly.
